It would be between the Rukus and the Caly 3 for me and it would depend on my environment and usage.
I would go with the Rukus if/because:
SD was an issue
I like HUGE pocket knives
Axis is fun
The changeable scales were worth it to me (too expensive IMO)
I would go with the Caly 3 if/because:
Sheeple were a concern
SD was not a concern (at least with using a knife for SD)
Grip was not an issue (the CF on the Caly is slicker than most handles)
I was more into gents knives
I preferred light knives
Personally I would go with the Caly 3, but for my own situation. Everyone's different and all of the choices you have are good ones. I'm not a big fan of liner locks and Al Mar knives, which is why I left them out of consideration.
